Transparent monitoring of power quality and energy consumption
The LINAX PQ3000 combines the characteristics of a power quality measurement device with functions for comprehensive energy consumption and condition monitoring. It stands out by the display quality and intuitive operation.

The modern, multi-lingual design and the high-resolution colour TFT display support the user in data analysis on site. The integrated webserver allows remote access to all measured data and the parameterization of the device. The device provides a wide functionality, which can be extended further by means of optional components.

Modbus/RTU interface
For measurement acquisition via control system

Process I/Os 
In addition to the standard I/Os (1 digital input, 2 digital outputs) up to three I/O extensions can be implemented in the device. You may select from:

  • 2 relay outputs
  • 2 analog outputs ±20mA
  • 4 analog outputs ±20mA
  • 4 S0 digital inputs active or passive

Uninterrupted power supply (UPS)
Provides power supply for five times 3 minutes if power fails

Data analysis
LINAX PQ3000 stores the acquired power quality data in the standardized Power Quality Data Interchange Format (PQDIF) according to IEEE 1159.3. Using the SMARTCOLLECT PM20 software the content of these files can be displayed, stored in a database and analyzed. A conformity report can be prepared as well.

Using the link the free of cost software PQDiffractor of Electrotek Concepts may be downloaded (registration required). By means of this software data of the PQDIF files can be analyzed, saved in CSV format or exported as a graphic.
